Title: Improvements in refrigerating machine compressors and refrigerating devices using such compressors
IPC: F04B45/04
Filed: 1936-07-21
Abstract: 478,072. Diaphragm compressors; diaphragm pumps. GOLD, R. July 21, 1936, No. 20224. Convention date, July 22, 1935. [Classes 8 (i) and 102 (i)] [Also in Group XXIX] A refrigerating-machine compressor primarily intended for small refrigerating units is of the liquid-actuated diaphragm type, a plurality of diaphragms and a slow speed motor being used so as to obtain substantially isothermal compression of the refrigerating agent. The diaphragms 2, Fig. 1 are mounted in casings 1 superimposed in a container 10 the liquid in which is put under pressure by a piston 24 reciprocated in a cylinder 12, communicating with the container, by crank 13. The pressure acts through perforations in the casings on the upper sides of the diaphragms, the lower sides of which are connected by pipes 5 and pipe 6 with chamber 7 containing a suction valve 9 and delivery valve 8. The piston 14 is hollow so as to form a reservoir, and carries an auxiliary pump 22, 23, 25, 26 actuated by linkage 24 from the crank 13 so that at each stroke of the piston 14 liquid is pumped from the reservoir therein into the container 10 to replace leakage losses ; excess is returned to the reservoir in the piston 14 through valve 27 and pipe 28, the former also acting as a pressure-relief valve. The compressed refrigerant passes through the valve 8 to the pipe coil 15 of a condenser in which it is cooled and condensed ; it then passes by pipe 16 and float valve 17 to the evaporator 18 ; this is arranged in the space 19 to be cooled; and in it the refrigerant evaporates with absorption of heat, then flowing through pipe 20 into jacket 21 and thence to suction valve 9. The pipe coil 15 and jacket 21 act as a heat-exchanger to minimize condensation within the diaphragm casings : the container 10 and cylinder 12 are insulated at 29 for the same object. The condenser 15 is arranged at a lower level than the compressor, so that any condensate which does form in the latter, as for example after an idle period, can drain away. In a modification Fig. 2, the diaphragm chambers and the various connections are formed in plates 31, 32, 33 superimposed to form a column, which may be coated with insulating material. The end plates are formed with reinforcements 34, 35. To reduce the clearance, each individual diaphragm chamber may be provided with its own suction and delivery valves. The Specification as open to inspection under Sect. 91 includes the application to compressing or exhausting gases generally and to liquid pumps. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 111,105, [Class 8 (i)].

Abstract: 1,027,448. Feeding sheets. W. F. WARD. May 24, 1963 [July 16, 1962], No. 20855/63. Heading B6B. A carton blank is separated from the bottom of a stack by a continuously moving endless belt 12 passing over a vacuum chamber 28 when spaced gates 20 are pivoted away from the stack to permit the bottom blank to pass thereunder. The chamber 28 comprises a rear compartment 60 permanently connected to a source of suction 64 and intermediate and front compartments 66 and 68 open adjacent the belt 12. A constantly rotating value 30 places the compartments 66 and 68 in communication with the compartment 60 one after the other whereby the bottom blank is fed away from the stack. As the leading edge of the blank passes over the compartment 68, the suction is switched from compartment 66 to compartment 68 so that suction is not applied to the next blank in stack. This prevents double feed. The gates are secured together by a common crossmember 80 and supported by parallel links 76, 78. Links 76 are rigidly fixed to a shaft 22 supported at each end on bearings. A twoarmed lever 84 is pinned to the shaft 22, Fig. 6, one arm 86 being attached to a block 88 slidably mounted on an arbor 90 and the other arm 106 being pivoted to a notched lever 108. A second two-armed lever 102 pivoted at 104, is attached at its upper end to a block 98 slidably mounted on the arbor 90 and is provided at its lower end with a cam follower roller 118. The lever 102 has an abutment 114 which co-operates with the notch 110 in lever 108. In operation, a lobe 122 of a cam 116 keyed to the shaft 74, rotates the lever 102 anticlockwise to move the arbor 90 to the left against the action of spring 92, while maintaining the lever 84 stationary. Finally, a projection 124 on lever 102 engages the lever 108 to release it from the abutment 114 and give the shaft 22 a rapid rotational movement as the spring 92 expands. This swings the gates 20 away from the stack to release the bottom blank.

In an embodiment the studs are fed from the arcuate track 14 down a transfer track 16 to the escapement 18 where they are blown through a flexible tube 20 to a receiver 22 of a stud-welding tool 24 being then pushed into the chuck 26 by an internal plunger. The container 12 comprises a hollow member mounted on a shaft 34, Fig. 2, rotatably held in a bearing 32 on an inclined plate 30, the peripheral edge of the member 12 being slightly spaced from the plate 30 and having notches or openings therein to receive a stem of a stud. The heads of the studs are received between the edge and the plate and two studs may be held in a single notch. The studs are supplied by a supply shoot 54 through an opening 52 in the plate 30 to the interior 50 of the member 12, and the studs move into the notches as the member 12 is rotated by engagement of an extension 56 of the shaft 34 by a piston-rod 62 of a fluidoperated cylinder 66 acting through a one-way clutch 58. The studs move into the track 14 from the notches under gravity and centrifugal force and then feed by gravity through the T- shaped track 16 to the escapement 18 where they are individually received in a notch 72 in a transfer bar 74 which carries them to a track 76 down which they are blown by air from a passage 78 to enter the receiver 22 of the tool 24. The slide bar 74 is operated by the piston 80 of an air cylinder 82. The stepped arcuate edge 90 of a removable cover-plate 88 forms part of the track 14, the cover-plate being secured by quick-release fasteners 76 to allow easy access to the tracks. A single valve controls the air supply to the cylinder 66, the cylinder 82 and the passage 78.
